Do I need to change the oil in the car after a cylinder missfired?

Had one cylinder missfire. Drove it maybe10 miles with that problem. Just changed the oil last week. Someone told me I may have gas in the oil from the missfire? 2005 Ford Freestar with 100k.

Added (1). Did lugs, coil, and wires.

Added (2). plugs

Added (3). That doesn't even make since any sense. Ido't call a person that didn't make it through high school and drinks a 12 pack a nigh a professional, or a dealer that chargesges you $400 to change 2 spark plug. A profesionl is a doctor or a lawyer. A car mechanic sn't a "Professional." He's a car mechanic. With that said, I'm going to the "Professional" hamberger maker at McDonald's, because I wouldn't want to do that myself.

1999 chevy blazer 4x4,.3?

The engine blew up in my 1999 Blazer, it had over 177,000 miles on it and it spun a bearing! My daughter's boyfriend put another 4.3 in it with 88,000 miles! Is 88,000 miles a lot of miles for a 4.3? The truck is back on the road again and running good! I don't know a whole lot about those 4.3s! Until I got this Blazer I always had ford trucks!

I have 1 more year to pay off my car should i start car shopping now?

So my 04 jeep GC with 160k owing $6,000 will be paid off by May of 2017, Should i start car shopping now that way once it's paid off for. I can just trade it in somewhere and take that money to make my payoff lower on the new car?
Obviously big dealers won't give me a loan but small ones can. I even went to verify with them…

Added (1). Like for example these guys said $2500 down and $500 a month for like 3 years… Might not do it though…

What's better, Ford or Honda?

People told me ford's (excluding trucks) can be problematic compared to other makes. But I really like Ford, and don't know if this is my sense or heart talking but think Ford is the best of all. Plus, some guy told me Ford parts last long. IS there any truth to this or is this guy playing with my mind?
